DM1224 Hematocrit Centrifuge

The Hematocrit Centrifuge (DM1224) is a specialized high-speed benchtop centrifuge designed for hematocrit determination, packed cell volume (PCV) measurement, and microvolume blood sample processing in clinical diagnostic and research laboratories . Operating at speeds up to 12,000 rpm (13,680 × g) with a maintenance-free brushless DC motor, this centrifuge features a dedicated 24-place AC24 capillary rotor specifically engineered for standard hematocrit capillary tubes .

For the hematologist and clinical laboratory scientist, the DM1224 enables precise measurement of packed cell volume—a critical diagnostic parameter for screening and monitoring anemia, polycythemia, dehydration, and other hematological disorders . The microvolume capability (50-75 μL blood samples) makes this centrifuge ideal for pediatric, neonatal, geriatric, and critical care patients where blood conservation is essential . The integrated rotor design with optional hematocrit reader allows direct measurement of PCV values, providing rapid results for clinical decision-making .

The centrifuge features microprocessor-controlled operation with precise speed control (500-12,000 rpm, increment: 100 rpm), LCD display with speed/RCF switchover, and programmable run times from 10 seconds to 99 minutes or continuous operation . The Pulse key enables instantaneous centrifugation for quick spin-down needs, while the timer logic ensures accurate separation times by commencing once set speed is reached . Acceleration and deceleration are completed in 40 seconds each, optimizing cycle times for high-volume clinical laboratories .

Safety features include double door lock system (door interlock) preventing operation with open lid, over-speed detection, and automatic internal diagnosis, with CE safety certification . The high-strength metal rotor with excellent dynamic balancing ensures quiet, stable operation at high speeds .

With a compact footprint (364 × 280 × 213 mm), lightweight design (8.5 kg), and 24-tube capacity, the DM1224 provides reliable, specialized performance for hematocrit determination, PCV measurement, and microvolume blood processing—supporting patient diagnosis across clinical hematology, pediatrics, oncology, and transfusion medicine .
